I’m aware. When I say “progressive forces” talking about groups or individuals who are playing a role in leftist aims even if those groups aren’t explicitly communist. Iran for instance is by no means a socialist state, but it is nonetheless a progressive force in the sense of countering imperialist influence in the middle east. Same can also be said for any number of groups that aren’t necessarily communist, such as unions and civic organisations, but may at times share common goals with the left.
